Description

Description

Description: This SGP1 monoclonal antibody reacts with human c-ErbB3, which is also known as HER3. This epidermal growth factor (EGF) receptor family member is expressed on normal human tissues, particularly on neurons and cells of the gastrointestinal tract. c-ErbB3 is overexpressed in a variety of cancers, including breast, ovary, and gastrointestinal carcinomas. Upon binding its ligand heregulin beta-1, c-ErbB3 is activated by heterodimerization with ErbB2 or EGFR1. Dependent on PI3K signaling, c-ErbB3 mediates tumor cell invasion, intravasation, and metastasis. Expression of this cell surface receptor has been used as a prognostic marker for breast cancer. The SGP1 antibody has been reported to stimulate anchorage-independent growth of breast cancer cell lines. Applications Reported: This SGP1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This SGP1 antibody has been pre-titrated and tested by flow cytometric analysis of the MCF7 cell line. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor® 710 can be used in place of PE-Cy5, PE-Cy5.5 or PerCP-Cy5.5. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm). Please make sure that your instrument is capable of detecting this fluorochrome. Fo...

ErbB3 (c-erbB-3/HER-3) is a member of the type I family of growth factor receptors and binds to ligands in the heregulin family. ErbB3 is over-expressed in a variety of tumors in the prostate, bladder, breast, stomach, pancreas, and colon. Heregulin and EGF stimulate tyrosine phosphorylation of c-erbB-3 to different extents. The ErbB3 gene is located on the long arm of human chromosome 12 (12q13) and is transcribed into a 6. 2kb mRNA which is translated into a 160/180 kDa glycoprotein. The ErbB3 gene encodes a transmembrane receptor tyrosine kinase due to alternative splicing and forms heterodimers with other EGF receptor family members that have kinase activity. Heterodimerization leads to the activation of pathways that lead to cell proliferation or differentiation. Alternate transcriptional splice variants encoding different isoforms of ErbB3 have been characterized. One ErbB3 isoform lacks the intermembrane region, is secreted outside the cell, and acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.
